Buzz is that Katrina insisted on having good friend Ayananka Bose shoot the ad. Apparently, the actress' reasoning was that Bose shot her best from all angles. However, the ace cinematographer chose to maintain a dignified silence when we contacted him.

He said, "Nothing like that happened. It's a wrong story." When probed about the messages on his Twitter page, Chandran didn't respond.

Miffing Karan Johar?

Buzz was that Karan Johar didn't take it lightly when Katrina kept director Ayaan Mukerji waiting before finally saying no to his production 'Yeh Jawani Hai Deewani' opposite Ranbir Kapoor.

An industry source points out, "That's when Ayaan and Karan cast Deepika Padukone in the movie. Karan wasn't too pleased. So to appease him, she instantly agreed to do the 'Chikni Chameli' item song in 'Agneepath'."

Saying no to Prakash Jha

To further make things right with KJo, Kat rejected Prakash Jha's 'Chakravyuh' in favour of Karan's 'Dostana 2'. The actress apparently wanted to keep her onscreen pairing with Abhishek Bachchan exclusive.

Our source adds, "Also, she was upset with reports of Prakashji praising Deepika's dubbing for 'Aarakshan'. That's what prompted stories about how she had also dubbed very well for Raajneeti, specially her long speeches, besides working hard to give her best performance for the political drama."

Katrina says...

Talking about her alleged refusal to do Jha's next, Katrina says, "I've not yet been offered the film. So the question of refusing it for any reason doesn't arise."

About ousting Chandran, the actress who is currently shooting in Cuba for 'Ek Tha Tiger' clarifies, "Recently I shot another ad with Raviji. I've never interfered in the setting of a team and never will. As a professional, I go to the sets, shoot the commercials and leave after pack-up."

About rejecting 'Yeh Jawani Hai Deewani' and then doing her 'Chikni Chameli' act to appease KJo, the actress says, "I don't know why it's being brought up again now. There are no problems between me and Ayaan or Karan."
